Air-powered hopper gun
A hopper, four nozzles, and your compressor
You load the hopper with mixed mortar, open the brass valve, and compressed air throws it at the wall through four nozzles. That is the whole mechanism.
There is no motor, no pump, no cord and nothing to plug in. It is the tool trades reach for on scratch and brown coats, for knocking a stucco texture onto block, and for getting render into corners and overheads where a hawk and trowel turn into a wrestling match.
How it works
Three moves, start to finish
Load the hopper
Tip mixed mortar in through the open top. The hopper hangs off the front of the wand, so your forward hand carries the weight and your back hand steers.
Open the valve
The brass lever is a ball valve, not a trigger. Crack it open and the air runs, close it and it stops. You meter the flow with the lever.
Sweep the wall
Keep it moving in overlapping passes, about a forearm off the surface. A stiffer mix lands heavier, a wetter mix lands finer.
What it sprays
Mortar, stucco, plaster and render
Cement mortar, stucco and plaster, thick or fine depending on how you mix it. The four nozzles are sized for a mix carrying aggregate, which is exactly why a thin coating runs and a lean mix sputters.
Block, brick, concrete, stone and lath all take it. Owners who have reviewed this tool used it for stucco on a house exterior and for shooting a concrete mix over a fieldstone foundation.
Before you buy
What is not in the box
This is the part most listings bury, and it is the usual reason a tool like this goes back.
- No air compressor. The supplier rates the gun for 4–6 bar — roughly 58–87 psi — fed from a 50–100 litre (13–26 gallon) tank. A small pancake compressor will run it in bursts and then spend the rest of the day catching up. Two owners here ended up teeing two compressors together to spray without stopping.
- No air hose, and no quick coupler. The inlet is a plain brass hose barb on the end of the wand. If your shop runs US quick-connect fittings, you are supplying your own adapter or hose clamp. Several owners did exactly that and said so in their reviews.
- No mortar. You mix your own, and you mix it wetter than you would trowel.
- No eye protection or gloves. Wet mortar leaves the nozzles fast and some of it comes back. Wear both, and more so overhead.
The build
Four nozzles in a cast manifold
The hopper is polished stainless steel with a seamed front face and a screwed base band. The nozzle block across the lower lip is cast alloy and carries four rubber tips in a row — that row is what spreads the pattern instead of firing one wet rope at the wall.
The wand comes apart at three threaded joints: hopper to tube, tube to valve, valve to inlet grip. It breaks down to fit a van or a job box instead of riding across the back seat fully assembled.
Clean it out the moment you stop. Mortar sets in a nozzle as readily as it sets on a wall; one owner keeps a length of stiff wire on the job to pick the jets clear between loads.
Specifications
What we can confirm
Hopper capacity, overall length, weight and air consumption in CFM are not published by the supplier, so they are not stated here. If you need a hard CFM figure before you buy, ask us and we will get it from the factory rather than estimate it.
Honestly
Where this is the wrong tool
- Fine finish coats. It lays texture, not a polished skim. If you want flat, you are still going back over it with a trowel.
- Small patches. Mixing, loading, hooking up air and then cleaning the gun costs more time than the patch is worth.
- Drywall texture. Different category of tool. A texture gun runs one adjustable orifice with interchangeable tips; this has four fixed nozzles sized for mortar.
- Paint. It is not a paint sprayer. It is built for cement mortar, stucco, plaster and render.
- Zero waste. Expect material on the ground. One owner laid the rubber back of an old rug under the work so the fallout could be scooped up and reused.
